Tool Parts not moving with arms (R6) please help

I am trying to make the arms move with arms (looking at mouse position)

but this happen:

The animation I use for this tools is:

How to animate Tool Parts (Guns, Knifes etc.)

Hello everybody! I’m Headstackk, I’ve been creating and making firearm weapons on Roblox for a while. I’ve also created the game Weaponry. In this post, I will briefly explain how to get started to animate a weapon on Roblox. I have already briefly explain how on this DevForum post, but I’d like to make a new post to clarify everything and explain it step by step. In most of the Roblox Shooter games (Excluding advanced shooter games such as Phantom Forces), I observed that they usually make a …

This is the script I am using for move arms.

Local script:

local run = game:GetService("RunService")

run.RenderStepped:Connect(function()

		if equipped then
			local rightX, rightY, rightZ = char.Torso["Right Shoulder"].C0:ToEulerAnglesYXZ()
			char.Torso["Right Shoulder"].C0 = (char.Torso["Right Shoulder"].C0 * CFrame.Angles(0, 0, -rightZ)) * CFrame.Angles(0, 0, math.asin((mouse.Hit.p - mouse.Origin.p).unit.y))

			local leftX, leftY, leftZ = char.Torso["Left Shoulder"].C0:ToEulerAnglesYXZ()
			char.Torso["Left Shoulder"].C0 = (char.Torso["Left Shoulder"].C0 * CFrame.Angles(0, 0, -leftZ)) * CFrame.Angles(0, 0, math.asin((-mouse.Hit.p - -mouse.Origin.p).unit.y))
		end
	end)

I dont know if is because the animations I am using but I dont think is because of that.

The animations system are basic

*Server Side*

game.Players.PlayerAdded:Connect(function(plr)			
	plr.CharacterAdded:Connect(function(char)
		local M6D = Instance.new("Motor6D")
		M6D.Name = "ToolGrip"
		M6D.Parent = char.Torso
	end)
end)

game.ReplicatedStorage.ConnectM6D.OnServerEvent:Connect(function(plr,location)
	local char = plr.Character
	char.Torso:FindFirstChild("ToolGrip").Part0 = char.Torso
	char.Torso:FindFirstChild("ToolGrip").Part1 = location
end)

game.ReplicatedStorage.DisconnectM6D.OnServerEvent:Connect(function(plr)
	plr.Character.Torso:FindFirstChild("ToolGrip").Part0 = nil
	plr.Character.Torso:FindFirstChild("ToolGrip").Part1 = nil
end)





*Local Script*

tool.Equipped:Connect(function()
	----Animations----
	local char = plr.Character or plr.CharacterAdded:Wait()

	game.ReplicatedStorage.ConnectM6D:FireServer(tool.ToolsParts.BodyAttach)

	char.Torso.ToolGrip.Part0 = char.Torso
	char.Torso.ToolGrip.Part1 = tool.ToolsParts.BodyAttach

	local Humanoid = char:FindFirstChild("Humanoid")  
	idle = Humanoid:LoadAnimation(script:WaitForChild("Idle"))

    idle:Play()
end)

This is how the tool looks like:

How would I make a players arm move depending on the y axis of the mouse? (R6)

So I have been looking for a solution to this for a year now, and I still don’t get how this is done. Some use trigonometry for this, which I barley understand. I’m also not the best with cFrame. I have found many topics similar to this but still will not conclude a full solution to this that is easy for me to comprehend. So anyways, as an example in text, the r6 arm would move up or down depending on the position of the mouse in the y axis. The higher it is, the more it would rotate up. The…

as i can see, you parented to character Torso, try to parenting to RightHand or LeftHand, because since that thing is attached to your torso, if you move your torso, the minigun will move, [in this case, moving the arms will not animate the minigun]

[correct me if i said something wrong]

char.Torso:FindFirstChild("ToolGrip").Part0 = char.Torso -- Change Torso to RightHand of the humanoid
--and do that with the rest 
	char.Torso:FindFirstChild("ToolGrip").Part1 = location

[ToxicalGamer2006]

I mean I dont think that can help because I am not using “Handle”

[ToxicalGamer2006]

the rest is other Motor6D for every arm?

[ToxicalGamer2006]

this is what happen

[Moleza]

Try this: (changed  torsos) 
game.Players.PlayerAdded:Connect(function(plr)			
	plr.CharacterAdded:Connect(function(char)
		local M6D = Instance.new("Motor6D")
		M6D.Name = "ToolGrip"
		M6D.Parent = char.RightHand
	end)
end)

game.ReplicatedStorage.ConnectM6D.OnServerEvent:Connect(function(plr,location)
	local char = plr.Character
	char.RightHand:FindFirstChild("ToolGrip").Part0 = char.RightHand
	char.RightHand:FindFirstChild("ToolGrip").Part1 = location
end)

game.ReplicatedStorage.DisconnectM6D.OnServerEvent:Connect(function(plr)
	plr.Character.RightHand:FindFirstChild("ToolGrip").Part0 = nil
	plr.Character.RightHand:FindFirstChild("ToolGrip").Part1 = nil
end)





*Local Script*

tool.Equipped:Connect(function()
	----Animations----
	local char = plr.Character or plr.CharacterAdded:Wait()

	game.ReplicatedStorage.ConnectM6D:FireServer(tool.ToolsParts.BodyAttach)

	char.RightHand.ToolGrip.Part0 = char.RightHand
	char.RightHand.ToolGrip.Part1 = tool.ToolsParts.BodyAttach

	local Humanoid = char:FindFirstChild("Humanoid")  
	idle = Humanoid:LoadAnimation(script:WaitForChild("Idle"))

    idle:Play()
end)

You have to use rigid constraints to connect the minigun to the player.

@Moleza

char.RightHand.ToolGrip.Part0 = char.RightHand
	char.RightHand.ToolGrip.Part1 = tool.ToolsParts.BodyAttach

It works but…

[ToxicalGamer2006]

from the bodyAttach to the arm?

[Moleza]

you will need to animate the minigun again, btw

[ToxicalGamer2006]

Oh ok thank you let me just test it.

[ToxicalGamer2006]

It works just fine… I think in something about weld with arms but I didnt tried but now I see it works very fine thank you.
